The right size for a solar system has always been a matter of concern. The answer relies on multiple factors. Many people assume available space is the main consideration, but space matters less than you might think; budget plays the bigger role. A useful starting point is knowing how many solar panels you need.
To be on the safe side, it is often better to choose larger panels, as they can convert energy on a bigger scale. In our experience, larger solar systems pay off with a good return on investment thanks to the extra kilowatts they produce.
If a client has a fixed budget but plenty of space, we usually suggest a system larger than 5kW. Ultimately, the decision rests with the client. On average, a 5kW solar system made up of 20 panels can produce roughly 250W per panel, and the quality of the panels also affects how much energy they generate.
What is the most recommended solar system size?
As mentioned above, a 5kW solar system is usually efficient enough to power an entire house. Open areas such as rooftops are a prerequisite for these larger setups.
Are there benefits to a bigger solar system?
According to many experts, the higher output of a larger system brings several benefits over a smaller one. The main advantages of installing a bigger solar system are:
- Lower maintenance cost
- Reduced cost per kilowatt
- Highly reliable
- Faster payback
- More energy production
Final verdict
An average house consumes more than 18 kWh of energy per day during winter, so it can be worth installing batteries to store energy for cloudy days. That decision is best made with professional advice. If you are also exploring storage, our Tesla Powerwall 2 review is a good read.
